Abstract:
Widespread, highly radioactive Devonian shales in the Appalachian Basin contain abundant organic matter and commonly contain hydrocarbons that are sources of natural gas. The shales are gas-productive in eastern Kentucky and southwestern West Virginia. Correlation of subsurface shale units in the basin is difficult because of unconformities and complicated facies changes, but such correlation may lead to the location of additional amounts of gas.
A series of stratigraphic cross sections through the western half of the Appalachian Basin depicts the subsurface relations between tongues of dark shale on the east and massive thick shale units farther west.
